Sausage stuffer



Patented Sept. 27, 1932 UNITED stares PATEN'E 9 m ADRIAN c. VAN HOOYDONK, or BUFFALO, new YORK, Assreiqort TOJOHN si vrirns v sons COMPANY, or BUFFALO, NEW YOB-K,-A CORPQRATION on NEW YORK SAUSAGE Application filed July 26,

This invention relates to improvements in sausage stuiiers of the type embodying a cylinder having a cover carried by a laterally?- swinging yoke, and a free piston or plunger operable in the cylinder by compressed air or other fluid under pressure.

One of its objects is to provide simple and reliable means for insuring a tight joint and safety seal between the cover and the cylin der. 3

Another object of the invention is the provision of effective andinexpensive means for clamping the cover-yoke in place, such means being arranged to render the top of the cylinder free and unobstructed when the cover is opened to load the device.

In the accompanying drawing :Figure 1 is a sectional elevation of a sausagestuiier constructed in accordance with my invention. Figure 2 is an enlarged horizontal section, taken substantially in the plane of line 22, Figure 1. Figure 3 is an enlarged vertical section taken on line 33, Figure 2.

Similar characters of reference indicate corresponding parts throughout the several views. In the stutter shown in the drawing, indicates the'uprightcylinder for receiving the meat-dough or other plastic'material and 11 the piston operable in the cylinder for ejecting the meat-dough therefrom through the customary spouts or nozzles 12. The lower end of the cylinder is closed and leading thereto is a pipe 13 for admitting the motive fluid under pressure to the cylinder'for raising the piston. 7

Applied to the open upper or delivery end of the cylinder, and securely fastened thereto by cap screws or otherwise, is a safetyring 14 which projects inwardly a suitable distance beyond the inner wall of the cylin der to form a stop or shoulder which prevents blowing out of the piston 11 should the operator neglect to turn off the motive fluid before opening orsremoving the usual cover 15 normally serving to seal the. open end of the cylinder. This cover is applied to the lower end of an upright clamping screw 16 provided at its upper end with a handle 17 and preferably carried by a horizontallysrurrna 192s, Seria1No.295, i68.

swinging yoke 18.,fulcrumed at one side to a pivot bolt 19 rising from a lug or boss 20 projecting laterally from the upper end of the cylinder 10. Intermediate its upper and lower ends this pivot bolt has a flange or collar 21 which engages a corresponding opening 22 in an ear 23 of the safety-ring 14 and bears at its lower side against the opposing top. side of the cylinder-lug 20. By this construction, the safety-ring, upon removing its fastening screws, can be swung to one side when desiredwithout wholly detaching it from the cylinder. 4 y

The free end of the cover-carrying yoke 18 is detachably locked to the cylinder for firmly-holding itagainst vertical or lateral displacement by means which preferably consist of bolts 24 and 25 secured, respectively, to the yoke and a boss 26 projecting from that side of the cylinder diametrically opposite the pivot-bolt 19 of the said yoke. In the normal closed position of the yoke shown by full lines in Figure 1, these bolts are in vertical alinement and their opposing ends terminate in heads 27,28 which are shaped toslidably interlock with each other as the cover-yoke is swung to its operative posi- 7 tion. For this purpose, each bolt-head is substantially hook or -L-shaped in cross section, the horizontal portion of one overlying that of the other, as clearly'shown in Fig ure 3, and being provided in their contiguous faces with companion tongues and grooves 29 and 30, respectively, which interlock with one another to reliably hold the yoke against vertical displacement. These tongues and grooves are shaped circumferentially relatively to' the pivot 19 of the yoke, as shown in. Figure 2, so that as the latter is swung laterally over the cylinder, these parts will properly register. In order to center the yoke in its operative position over theyoke and prevent its lateral displacement, a lo-' eating device, preferably in the form of a ball 31 is provided. This ball is arranged in an opening inthe head of the bolt 25 and is backed by a coil spring 32 for urging it into a .oorresponding'seat or depression 33 in the opposing sides of the head of the bolt 24.

The cover 15 is adapted, in its sealed or closed position, to seat itself into'the opening in the safety-ring 14. I provide a double safety seal for this purpose and to this end the opening in the safety-ring has upper and lower conical or beveled seats 34, 35, respectively, the lower seatconverging downwardly and inwardly at a slight,angle, say about nine degrees, and the upper seat conv ging in th m d ction tabc t a forty-five degree angle, a s-shown in Figure 3. The periphery of the cover "is provided with corresponding beveled joint edges36, 37 cooperating with the companion ring seats. The lower joint edge 37- ,ofzthecoyer s by acting as a safety seal and effectually guarding against blowing out of the cover under the high pressure existing in the :cylinder 10 ofthe stuifer.
